Revealing the impact of self-organized collective behavior [1]}, [2]} on contagion processes is essential for understanding the functional aspects of a variety of behaviors exhibited by biological collectives (such as the risk-related behavior described in [3]}).
In bacterial swarms, for example, the spreading of genetic information (through direct contacts or via bacteriophages [4]}) is conditioned by the self-organized coordinated motion and cluster formation that emerges from simple physical interactions [5]}, [6]}, [7]}.
These genetic propagation dynamics are believed to play an important role in key processes such as the spread of antibiotic resistance in bacterial populations [8]}, [9]}.
A better understanding of this type of phenomena will thus require further studies of the interplay between infection spreading and collective spatiotemporal dynamics that can be built on the results obtained in our work.
